Table 3. Association of standardised leadership score with incident IHD among employees after adjustment for different risk factors at baseline*.

Adjustment variables in addition to age	Hazard ratio for IHD per 1 SD increase in leadership score(95% CI)
None	0.65 (0.49 to 0.87)
Education, supervisory status, social class, income	0.67 (0.49 to 0.90)
and physical load at work

cholesterol, total/HDL cholesterol ratio, triglycerides,
fibrinogen, diabetes
All of the above	0.63 (0.46 to 0.86)

*Only those with a minimum of 4-year exposure and no missing data in any of the predictors were included in these models (n = 1319, 40 events).

Ischaemic heart disease (IHD) included unstable angina. HDL, high density lipoprotein.
